Cleaner

This has been working great to avoid having my AC line clog or freeze. Great purchase!

I recently used the AC Drain Line Cleaner and was highly impressed. It effectively cleared my HVAC and fountain drink drain lines, improving performance and preventing clogs. The application was easy and quick, with clear instructions. This versatile and powerful cleaner is a must-have for anyone needing to maintain various drain lines. Highly recommended!

usually use bleach and warm water but decided to try this product. poured down the drain line per directions. not sure if it works any better than other products but hey no clogs which are very common in my area... we use ac non stop

We live in a Florida mid-rise that is 50 years old ... each unit has it's own HVAC/Heater unit. During a recent period of unusually high humidity, water started pouring out of the AC condenser. Before calling in a service company, we got on YOU TUBE and learned that one of the most overlooked areas of an AC unit is the drain line ... it can get plugged! Found this great product on trusty Amazon. Turned off the unit ... poured in a bottle ... and after about a half hour, turned unit back on ... UNIT NOW RUNNING LIKE NEW ... three weeks and not a single drop of overflow!!!

Easy to use

I have an older through the wall Kuhl AC. The unit has a small opening that allows the water to drain to the back of the drain pan. I had to have someone take the unit out and clean out the blocked opening. Last year it blocked again and I had to manually drain the pan several times a day to stop an overflow. One bottle at the beginning of warm weather cleared the blockage and it is draining properly! No more overflows!

Used a borescope on the drain line before using this product and then poured this product in the line. This did absolutely nothing and looks identical to how it did prior. Save your money and use bleach or vinegar that is cheaper and does the same thing.

After the great reviews i was thinking i was gonna be good. Didnt help my case. water still backing up.
